Because compromise isn"t an option at Klipsch, the Reference Series RB-61 lets listeners experience all the power, detail and emotion of cinematic spectacles and riveting concert performances. Exclusive Tractrix Horns have always been the key component of this critically acclaimed series. In the RB-61, this technology has been refined to include improved throat geometry for a more genuine, lifelike sound. Behind the horn lies a 1-inch titanium tweeter with a large ceramic motor structure to provide a unique combination of precision, clarity and effortless power. The RB-61 employs a 6.5-inch woofer for a solid bass foundation. This Cerametallic woofer with inverted copper dust cap exhibits a very high stiffness-to-mass ratio and superb damping characteristics. The RB-61"s front-firing port eliminates turbulence noise and makes installation into custom cabinetry a breeze. Increased baffle ribbing around the horn mouth dramatically improves acoustics across the sonic range. Available in a black woodgrain vinyl finish, the RB-61 comes with a low-diffraction, magnetically attached grille to further accentuate the elegance of these speakers.
